How am I supposed to compile the project?

[Lucide]

The readme says to run

mkdir build
cd build
cmake ..
make
make install

But I don't understand if they are supposed to be used on Windows:

run ascii-paint.exe from within bin/

or Linux?

make
make install

Or perhaps within Windows, but generating makefiles for make for Windows?
I can't compile anyway on both Visual Studio (2019) and Ubuntu (gcc 7.4.0), due to compilation errors.

What am I doing wrong?

Good question! I last touched this project many years ago, so I have no idea off the top of my head. Unfortunately I have no time right now, but the project definitely deserves some TLC. Until then maybe consider REXPaint(?).

ahahah, I see, no problem :)
In fact I got here right from REXPaint's manual:

There are a number of ASCII art editors available on the web, but most suffer from poor usability or small feature sets (one notable exception being eigenbom's awesome fork of ASCII Paint).

When the time comes, I'll check back!

Oh haha, well I think Josh has been updating REXPaint over the years so it's likely to be superior.
